Find the slope
-5/4
4/5
-4/5

The slope of the line is ⇒ B

Step-by-step explanation:

You can find the slope of a line using any two points on the line (x1, y1) 1nd (x2, y2) by using this rule

Let us use this rule to answer the question

From the attached graph:

∵ The given line passes through points (-1, -2) and (4, 2)

→ That means point (x1, y1) = (-1, -2) and point (x2, y2) = (4, 2)

∴ x1 = -1 and x2 = 4

∴ y1 = -2 and y2 = 2

→ Substitute their values in the rule of the slope above

∴

∴ The slope of the line is

We have 5 digits. So there are: 5 * 4 * 3 * 2 * 1 = 120 five - digit numbers if we use each digit once. And : n = 120 ( all incomes )
If the resulting number is divisible by 4, then the last 2-digit number must be divisible by 4:  24, 28, 32, 48, 72, or 84 ( 6 in total ). And the first 3 digits of those numbers can be ordered in 3 * 2 * 1 = 6 ways.
m = 6 * 6 = 36 ( favorable incomes )
Probability = m / n = 36 / 120 = 3 / 10.
The probability is 3 / 10.
